Let's just be glad that Singler didn't tear a knee ligament or anything on this play, because it would've looked bad on those Warriors laughing in his face near the end of the Vine. As if it wasn't bad enough for Singler, his hustle also got him whistled for a foul on the play.
This was not nearly as embarrassing as the DeAndre Jordan dunk on Brandon Knight last year, but considering the fact that Thompson isn't a prolific dunker and Singler's funny fall at the end, it is pretty highlight worthy nonetheless.
